Hi,
What do the diodes do in this circuit?
It looks like some sort of hysteresis section, but simulating it and changing the resistor to ground or either of the resistors in series with the diodes seems to alter either the rise time and/or final fall time (similar to changing the capacitor to the right of the diode/resistor stage).
Removing the diodes didn't really change any voltage or current values, it only removed the slow tail after the fall from the NMOS load being on.

Thanks.
